Math:

You can try to reason about the theorems in the textbook yourself. This will not only improve your proof ability, but also deepen your understanding of the formula. There are many exercises. Basically, after each class, you have to do after-school exercises (excluding the teacher's homework). The improvement of math scores and the mastery of math methods are inseparable from students' good study habits. Therefore, good math study habits include: listening, reading, exploring and doing homework. Listening: We should grasp the main contradictions and problems in the class, try to think synchronously with the teacher's explanation when listening, and take notes when necessary. Every time after class, we should think deeply and summarize, so as to achieve one lesson at a time. Reading: Be careful when reading. To understand every concept, theorem and law, examples should be linked with similar reference books to learn together, learn from each other's strengths, increase knowledge and develop thinking. Inquiry: Learn to think, explore some new methods after solving problems, learn to think from different angles, and even change conditions or conclusions to find new problems. After a period of study, you should sort out your thoughts and form your own thinking rules. Homework: Review first. Think first, then write, do a class of questions, understand a large area, do your homework carefully, and standardize your writing. Only in this way can you learn math well. In short, in the process of learning mathematics, we should realize the importance of mathematics, give full play to our subjective initiative, pay attention to small details, develop good math learning habits, and then cultivate the ability to think, analyze and solve problems, and finally learn mathematics well.

In short, it is a process of accumulation. The more you know, the better you learn, so remember more and choose your own method. I wish you success in your study!
